BACKGROUND

Biomarkers are molecular indicators of a specific biological property, a biochemical feature or facet that can be used to measure the progress of a disease or the effects of a treatment. For example, serum low-density lipoprotein (LDL) is a biomarker of cholesterol and blood pressure, while the P53 gene is a biomarker for cancer. For chronic diseases and conditions, such as diabetes and allergies, accurate diagnosis is particularly important, especially where the side effects of a treatment are severe.

Diagnostic tests using biomarkers as molecular indicators not only detect the presence or absence of the biomarker, but often must measure the exact concentration of a biomarker to determine whether an abnormal condition exists. Because of the requirement for accuracy, the process of sample collection, preparation, and analysis are often complicated and time consuming. Currently, blood-based assays for biomarker presence or activity are considered to be the “gold standard” for biomarker-type assays.

Despite the desire for accurate results, rapid, point of care analysis of biological samples using biomarkers is becoming increasingly important in the present medical environment due to the need for quick results.

DETAILED DESCRIPTION

For the purposes of promoting an understanding of the principles of the present disclosure, reference will now be made to the embodiments illustrated in the drawings, and specific language will be used to describe the same. It will nevertheless be understood that no limitation of the scope of this disclosure is thereby intended.

The disclosure of the present application provides various compositions, systems, and methods for biomarker stabilization and analysis. Specifically, formulations are disclosed herein, which function to preserve the level of diagnostic markers, such as biomarkers, in body fluids, from enzymatic alteration, or degradation. Additionally, methods for the collection and analysis of body fluids are disclosed. The methods and formulations disclosed herein can be used to improve the sampling and testing of a body fluid by conditioning the body fluids for the stabilization of specific biomolecules and/or drug metabolites. As used herein, the term “body fluids” includes fluids produced by the body, such as saliva, or fractions thereof, mucous secretions, tears, sweat, bile, semen, urine, vaginal secretions, exhalations, anal secretions, blood, plasma, serum and mixtures of thereof. Body fluids may also comprise cancer cells, peripheral blood mononuclear cells, lymphocytes, lymph fluid, and other tissue secretions or fluid.

Saliva

Saliva is clear, viscous fluid with a slightly alkaline pH and a pI range from 11.5-3.0. It is hypotonic, composed of about 99.5% water, and also contains ions (e.g., K⁺, Na⁺, Ca²⁺, Mg²⁺, H⁺, Cl⁻, HCO₃ ⁻, I⁻, F⁻, HPO₄ ²⁻), and small organic molecules (e.g., ureas, hormones, lipids, DNA, and RNA). There are multiple contributors to the composition of saliva. Saliva has a complex “proteome”-10⁶ D glycoproteins to 1000D peptides. It contains secretory products of salivary glands, products of B cells, PMNs, epithelial cells, and bacteria. Major (e.g., parotid, submandibular, and sublingual) and minor (e.g., palatine and retromolar) glands contribute to the composition of saliva, along with extraneous contributors such as gingival crevicular fluid, serum proteins, white blood cells and their byproducts, oral epithelial cells, oral bacteria, food debris and dissolved food components.

Saliva from different glands may differ in composition. For example, saliva from the parotid gland is dominated by serous secretory cells, whereas saliva from the submandibular and sublingual glands and minor glands are mixed serous or mostly mucous. There can also be qualitative and quantitative differences in saliva output that affect its composition. Glandular contribution to saliva is affected by level of gland activity. The amount of saliva secreted per minute or the salivary flow rate influences the concentration of the constituents as well as the proportion of the constituents from each of the three pairs of major salivary glands and the minor salivary glands.

I. Stabilizing Agents

According to at least one embodiment of the present disclosure, conditioning of body fluids for the preservation of diagnostic markers may be accomplished through the use of stabilizing agents, which may be incorporated into one or more carrier vehicles, such as rinses, gums, beverages, and confectionaries. For example, specific rinses and/or pre-rinses specially formulated according to the specific molecule or molecules (the diagnostic marker) to be detected in the body fluid, may contain a stabilization agent. The use of rinses and pre-rinses of the present disclosure to condition the body fluid may enhance the sensitivity for detection of specific diagnostic markers for clinical diagnosis. Additionally, this process may improve the signal-to-noise ratio for a better diagnostic yield. Further, each rinse/pre-rinse can be specifically formulated to reduce or prevent false positive and false negative results.

In at least one embodiment of a stabilizing agent of the present disclosure, the stabilizing agent may act to prevent/decrease the degradation, or reduction of activity, of diagnostic markers. In at least one embodiment, the stabilizing agent may be comprised of one or more Generally Regarded as Safe (GRAS) compound, as determined by the Food and Drug Administration of the United States of America, such as those listed in Table I. An exemplary embodiment of a stabilization agent may act to stabilize a diagnostic marker, and/or to bind to a destructive component to prevent the destructive component from degrading or decreasing the activity of the diagnostic marker.

In additional exemplary embodiments of the stabilization agent, the stabilizing agent may comprise at least 2, at least 3, at least 4, at least 5, at least 6, at least 7, at least 8, at least 9, at least 10, at least 15, at least 20, or at least 25 compounds which acts to stabilize the diagnostic marker, and/or to bind to a destructive component to prevent the destructive component from degrading or decreasing the activity of the diagnostic marker. Further, in various embodiments the stabilizing agent of the present disclosure may be present in at a level of between about 200 ppm to about 2,000 ppm, about 400 ppm to about 1600 ppm, about 600 ppm to about 1400 ppm, about 800 ppm to about 1200 ppm. Moreover, in at least one embodiment, the stabilizing agent may be present at a level of approximately 500 ppm.

According to at least one exemplary embodiment, the stabilizing agent may block at least one enzymatic activity of a destructive component. The destructive component may be one or more component of a bodily fluid which acts to degrade, or decrease the activity of a diagnostic marker. Further, the destructive component may be one or more Amylases, Lysozymes, Peroxidases, Glycosidases, Esterases, Proteases, and/or Peptidases. In an exemplary embodiment, the stabilizing agent may be a naturally occurring or artificial protease inhibitor, DNase inhibitor, or RNase inhibitor. Specifically, a natural stabilizing agent may include any component found from food products (including, but not limited to, the Solanaceae family), herbs, or spices that acts to decrease the effect of a destructive component. For example, exemplary embodiments of the natural stabilizing agents may be any of the inhibitors found in lima beans, soybeans, or avian eggs (such as ovomucoid glycoprotein protease inhibitors) (See Table II). Moreover, an embodiment of the stabilizing agent may also comprise a molecule which specifically inhibits the activity of a molecule which targets the diagnostic marker for degradation or inactivation. Further, the stabilizing agent may act to alter the composition of the body fluid (such as pH, or ion concentration) to decrease the degradation or inactivation of the diagnostic marker.

C. Exemplary Targets for Stabilizing Agent(s)

1. Amylase

Amylase is an enzyme that breaks down starch into sugar, and is found in such places as human saliva, where it begins the chemical process of digestion. The α-amylases are calciummetalloenzymes that are completely unable to function in the absence of calcium. Through acting at random locations on the starch chain, α-amylase breaks down carbohydrates into maltotriose and maltose from amylase. In animals, α-amylase is a major digestive enzyme that has an optimum pH of 6.7 to 7.0.

In at least one embodiment of a stabilizing agent of the present disclosure, the stabilizing agent may be an inhibitor of α-amylase. Further, the stabilizing agent may be active in a biological fluid, such as in saliva. In an exemplary embodiment, a stabilizing agent may comprise one or more of Fixanal® Buffer 6.0 (Sigma-Aldrich Co.), aluminum sulfate hydrate, aluminum hydroxide, bentonite, and aluminum potassium sulfate dodecahydrate.

2. Lysozyme

Lysozyme, also known as muramidase or N-acetylmuramide glycanhydrolase, is a glycoside hydrolase, that damage bacterial cell walls by catalyzing hydrolysis of 1,4-beta-linkages between N-acetylmuramic acid and N-acetyl-D-glucosamine residues in a peptidoglycan and between N-acetyl-D-glucosamine residues in chitodextrins. Lysozyme is abundant in a number of secretions, such as tears, saliva, human milk, and mucus. It is also present in cytoplasmic granules of the polymorphonuclear neutrophils (PMN).

In at least one embodiment, a stabilizing agent of the present disclosure may be an inhibitor of lysozyme. Further, the stabilizing agent may be active in a biological fluid, such as saliva. In an exemplary embodiment, a stabilizing agent may comprise one or more of Fixanal® Buffer 6.0 (Sigma-Aldrich Co.), bentonite, benzoic acid, and acetic acid.

3. Peroxidase

Peroxidase are a class of oxidoreductase enzymes that catalyze the oxidation of a compound by the decomposition of hydrogen peroxide or an organic peroxide. These peroxidases may be found in many different bodily fluids. For example, saliva contains both salivary peroxidase (SPX) and myeloperoxidase (MPO). These peroxides may act on a number of different diagnostic markers found in bodily fluids to mask the detection or analysis of the markers.

In at least one embodiment of a stabilizing agent of the present disclosure, the stabilizing agent may be an inhibitor peroxidase activity. Further, the stabilizing agent may be active in a biological fluid, such as saliva, blood, serum, or cancer cells. In an exemplary embodiment, a stabilizing agent may comprise one or more of aluminum sulfate hydrate, benzoic acid, and aluminum potassium sulfate dodecahydrate.

4. Insulin Resistance

In at least one embodiment of a stabilizing agent of the present disclosure, the stabilizing agent may preserve a diagnostic marker for insulin resistance and/or glucose intolerance. Further, the stabilizing agent may be active in a biological fluid, such as saliva. In an exemplary embodiment, a diagnostic marker may be one or more of α-hydroxybutyrate, 1-linoleoyl-GPC, palmitate, Glycine, 3-methyl-2-oxybutyrate. Moreover, a diagnostic marker may be any marker of early stage insulin resistance and glucose intolerance in a non-diabetic individual.

5. Galactose Oxidase

Galactose oxidase is a member of the family of oxidoreductaases, and has been shown to participate in galactose metabolism. Because of this activity, galactose oxidase may be used to detect mucin-like glycoproteins. These glycoproteins are a major component of mucus secreted by epithelial and glandular cells and are primarily responsible for the protective properties of the viscoeleastic mucous barrier. Mucins have been implicated in the process of cholesterol gallstone formation, and has been identified as having abnormal expression in some cancers.

In at least one embodiment of a stabilizing agent of the present disclosure, the stabilizing agent may be an inhibitor of galactose oxidase. Further, the stabilizing agent may be active in a biological fluid, such as saliva. In an exemplary embodiment, a stabilizing agent may comprise one or more of aluminum potassium sulfate dodecahydrate, 3-tert-butyl-hydroxyanisole, benzoic acid, and acetic acid.

6. Glycated Hemoglobin

Glycated hemoglobin (HbA1c) is a form of hemoglobin that is indicative of the average plasma glucose concentration over a period of time. Due to the transport of components of the plasma into bodily fluids, such as saliva, the level of HbA1c may be determined in bodily fluids in addition to plasma.

In at least one embodiment of a stabilizing agent of the present disclosure, the stabilizing agent may be an inhibitor of HbA1c degradation. Further, the stabilizing agent may be active in a biological fluid, such as saliva. In an exemplary embodiment, a stabilizing agent may comprise one or more of acetic acid, aluminum hydroxide bentonite, aluminum sulfate hydrate, aluminum potassium sulfate dodecahydrate, benzoic acid, caffeine, and 3-tert-butyl-hydroxyanisole, or a combination thereof.

IV. Methods of Biomarker Stabilization

In at least one embodiment of a method for stabilizing biomarkers, as described in FIG. 7, the method 700 comprises the step 702 of mixing a body fluid with an embodiment of a stabilizing agent. Optionally, the step of mixing a body fluid with a stabilizing agent may comprise the step 704 of introducing the stabilizing agent into the patient, such as through the oral cavity, so that the stabilizing agent mixes with the bodily fluid, and the step 706 of retrieving a body fluid comprising a stabilized diagnostic marker. In an additional exemplary embodiment of a method of stabilizing a diagnostic marker, the method comprises the step 708 of isolating a body fluid having a diagnostic marker, the step 710 of treating the body fluid with an embodiment of a carrier, such as a rinse, gum, or beverage, as described herein, and the step 712 of analyzing the diagnostic marker. Isolation of the body fluid may occur through any customary mechanism, including, but not limited to, rinsing, swabbing, suction, collection, and lavage. Further, the rinse in an exemplary embodiment of a method 700 of the present disclosure, may be ingested to stabilize a diagnostic marker present in the bodily fluid, such as in urine, semen, anal secretions, and vaginal secretions.

The step 702 of mixing a body fluid with a carrier may occur prior to, or after isolation step 708 of the body fluid. As an exemplary embodiment, a rinse may be used to rinse the mouth. Afterwards, the rinse containing the treated body fluid may be collected by spitting, suction, or other means. Alternately, expirated saliva may be mixed with a rinse to treat the saliva ex vivo. Similar treatment of body fluids may be performed with any type of body fluid.

In analyzing the treated body fluid, the diagnostic marker may be analyzed through any known means. Optionally, the analysis of the treated body fluid may include the separation of solid materials from soluble materials through means such as filtration, or by centrifugation. Analysis of the treated body fluid may use any appropriate technique, such as western blot analysis, Enzyme-Linked Immunosorbent Assay (ELISA), protein activity assays, reverse transcription polymerase chain reaction (RT-PCR), microarray, high pressure liquid chromatography, or any comparable assay to determine a characteristic of the diagnostic marker. Such an analysis, in an exemplary embodiment, may be of a modified product, a cleavage product, or cleavage pattern, of a diagnostic marker.

In an exemplary embodiment of the analyzing step 712, the treated body fluid may be placed in contact with an embodiment of a test strip, such as a nitrocellulose strip, prior to detection with an appropriate probe specific for the diagnostic marker. The nitrocellulose strip may be designed to trap or filter particulates in the body fluid. This may reduce or eliminate potential contaminants or other substances in the oral fluid that would otherwise reduce the signal to noise ration during the detection step. A probe (such as an antibody) with affinity to the diagnostic marker may be affixed or immobilized to a specific location on the nitrocellulose membrane for detection of the analyte. Utilizing standard principles of immunoassay detection (or nucleotide detection), the signal generated may be visible to the eye or detectable by an instrument.

In an exemplary embodiment of a method of analyzing a stabilized diagnostic marker of the present disclosure as depicted in FIG. 8, the method 800 comprises the step 802 of operating a system for the detection of a diagnostic marker in a body fluid, where the system comprises a diagnostic device having a plurality of test wells each capable of containing at least one diagnostic marker binding agent, and a detection device capable of interacting with diagnostic device, wherein the detection device is capable of detecting an interaction between the at least one diagnostic marker binding agent and a diagnostic marker. Following step 802, the sample of bodily fluid may be diluted in step 803 with a reagent which may contain an embodiment of stabilizing agent as described herein. At least one embodiment of method 800 further comprises the steps of: contacting 804 a sample of a bodily fluid with at least one diagnostic marker binding agent, incubating 806 the contacted sample in the test well at a first temperature for a pre-determined period of time. The step 804 of contacting of the sample of bodily fluid with at least one diagnostic marker binding agent may be accomplished through a magnetic field applied to the test well.

In at least one embodiment of method 800, the first temperature may be at room or at body temperature (such as about 22° C. or about 37° C.). The pre-determined period of time may, for example, be between five and fifteen minutes. The incubated and contacted sample may then be removed in step 808 from the plurality of test wells, and the test wells analyzed in step 810 to detect a binding event with the detection device. Alternately, a stabilizing agent may be incubated with the diagnostic marker binding agent (also referred to as a detection agent) prior to introduction of a bodily fluid. In at least one embodiment of the method, each diagnostic marker binding agent may have a different monoclonal antibody designed to bind a specific hapten molecule.

Following the detection of a characteristic of a treated diagnostic marker (the results of which may be termed a “profile” such as a “cancer profile”), the characteristic may in step 812 be compared to a standard value to determine the presence or absence of a disease state. The characteristic determined may be an activity level, the concentration of the diagnostic marker, or a particular modification, such as glycosylation or methylation.

Optionally, an embodiment of the method 800 may further comprise the step 814 of customizing a detection method through screening of applicable pre-clinical samples through a database of stabilizing agents/cocktails. Further, an embodiment of method 800 of diagnostic marker detection may further comprise the step 816 of comparing a level or characteristic (such as a predictable degradation products) of a diagnostic agent with a library of known characteristics. Moreover, an exemplary embodiment of method 800 may additionally comprise the step 818 of determining a diagnosis of a disease state using the compared characteristic. In at least one embodiment, a method of diagnostic marker detection may be automated, and capable of detecting at least about ten thousand samples in a twenty-four hour period. Method 800 in at least one embodiment, may be at least partially completed by a computer processor. Additionally, the processor may be in communication with at least one more processor and/or a computer database. For instance, in at least one embodiment of method 800, most of the steps of the method may be completed with or monitored by a computer processor. Moreover, method 800, in at least one embodiment, may use a computer processor to perform additional step 820 of generating a report by using a comparison of determined characteristics (such as a binding report where a comparison is performed of binding characteristics), and step 822 of delivering the report to a recipient (such as a user, or secondary processor).

EXAMPLES Examples 1. α-Amylase Inhibition Saliva Screening Method

At least one assay used for the detection of α-amylases activity, as used herein includes the use of a chromagenic substrate, 2-chloro-p-nitrophenol linked to maltotriose. Enzymatic activity of α-amylase on the substrate yields 2-chloro-p-nitrophenol, which can be measured spectrophotometrically at 405 nm. The amount of α-amylase activity present in the experimental sample is directly proportional to the increase in absorbance at 405 nm.

For the assay, test compounds are mixed with saliva, prior to the addition of α-amylase substrate. The test compounds, such as GRAS materials, are prepared at a concentration of 5,000 ppm in distilled water. Following this preparation, 300 μl of α-amylase substrate (Salimetrics α-amylase Assay Kit) that has been pre-heated to 37° C. is added to 20 μl of the test compound. To initiate the assay, 10 μl of a dilute (3.5%) or full strength (100%) saliva solution is added to the mixture. Following the initiation, each mixture is measured at 1 minute intervals using a spectrophotometer (such as Molecular Devices M5 reader) at 405 nm. Temperatures of the mixtures are kept constant at 37° C. during the assay.

3. Lysozyme Inhibition Saliva Screening Method

At least one assay used for the detection of α-amylases activity, as used herein includes the use of a Micrococcus lysodeikticus labeled with fluorescein. The assay measures lysozyme activity on Micrococcus lysodeikticus cell walls, which are labeled to such a degree that the fluorescence is quenched. Lysozyme activity can relieve this quenching; yielding increased fluorescence that is proportional to lysozyme activity.

For the assay, test compounds are mixed with saliva, prior to the addition of lysozyme substrate. The test compounds, such as GRAS materials, are prepared at a concentration of 5,000 ppm in distilled water. Following this preparation, 50 μl of lysozyme substrate at 1 mg/ml (Molecular Probes EnzChek Lysozyme Assay Kit) that has been pre-heated to 37° C. is added to 50 μl of the test compound. To initiate the assay, 50 μl of a dilute (3.5%) or full strength (100%) saliva solution is added to the mixture. Following the initiation, each mixture is measured at 1 minute intervals using a spectrophotometer (such as Molecular Devices M5 reader) for absorption at 494 nm and fluorescence emission at 518 nm. Temperatures of the mixtures are kept constant at 37° C. during the assay.

4. Lysozyme Inhibitor Assays

A series of GRAS compounds were tested using the Lysozyme assay protocol described above. The tested compounds are included in Table I. From the screen of GRAS compounds, four compounds including Fixanal® Buffer 6.0 (Sigma-Aldrich Co., CDI-030), bentonite (CDI-37), benzoic acid (CDI-40), and acetic acid (CDI-047) were shown to have Lysozyme Inhibitor Activity in dilute (3.5%) saliva (See FIG. 12).

5. Galactose Oxidase Inhibition Saliva Screening Method

At least one assay used for the detection of galactose oxidase activity, as used herein, includes the use of a chromagenic or fluorogenic substrate, such as with Amplex® Red (Molecular Probes). In an embodiment of the assay used herein, galactose oxidase catalyzes the oxidation of galactose at the C6 position and generates hydrogen peroxide (H2O2). The H2O2 then, in the presence of horseradish peroxidase (HRP), reacts with 1:1 stoichiometry with Amplex® Red reagent to generate the red-fluorescent oxidation product, resorufin. Resorufin has absorption and fluorescence emission maxima of approximately 571 nm and 585 nm, respectively, and because the extinction coefficient is high (54,000 cm-1M-1), the assay can be performed either fluorometrically or spectrophotometrically.

For the assay, test compounds are mixed with Amplex Red, reaction buffer, horseradish peroxidase (HRP) at 100 U/ml, and galactose stock solution (according to manufacturers recommended protocol, Molecular Probes A22179), prior to the addition of saliva. The test compounds, such as GRAS materials, are prepared under various concentration for testing. Following this preparation, 50 μl of the test compound solution (with Amplex Red, reaction buffer, and HRP) is added to 50 μl of saliva.

11. Peroxidase Assay

To determine the effect of various GRAS compounds as inhibitors of peroxidase activity, a standard assay using Amplex® Red (Life Technologies), which releases a fluorescent oxidation product. This oxidation product, named resorufin, has an excitation and emission maxima of approximately 571 nm and 585 nm, respectively, and because the extinction coefficient is high (58,000±5,000 cm-1M-1), it allows for the use with fluorometric or spectrophotometric assays.

The test compounds, such as GRAS materials or cocktails of same, were prepared at a concentration of 500 ppm in distilled water. For the assay, 50 μl samples of test compounds were mixed with 20-30 μl of saliva (either “pooled” or “unpooled”) prior to the addition of Amplex® Red. Following the mixture of the test compounds with saliva, 500 of Amplex® Red/HRP working solution (See Protocol for Invitrogen Assay #A22188, which is incorporated herein in its entirety), which has a concentration of 100 μM of Amplex® Red, is added to the test compound/saliva mixture. Following the initiation of the reaction, each mixture is measured at 1 minute intervals using a spectrophotmoter (such as a Molecular Devices M5 reader) for excitation in the range of 530-560 nm and fluorescence emission detection at approximately 590 nl, or for absorption at approximately 560 nm. Reactions were allowed to run for 30 minutes during these assays.

13. Diagnostic Devices

In an example of a diagnostic device, as shown in FIG. 30, a test slide with 28 test wells are spotted with 12 to 18 sets of diagnostic markers. These reagents may include diagnostic markers, or controls for the diagnosis. The diagnostic device, in this example, has four diagnostic markers spotted in duplicate, along with two positive and two negative control marker. Each marker is spotted with a competitor, such as anti-haptin, which binds the capture antigen particle to the marker. The device may have four different hatpin/anti-haptin systems to serve as the generic capture system. A unique haptin may be conjugated to a fully paramagnetic particle (PmMp). The PmMp is also coated with a capture monoclonal antibody (MAb) specific for the marker. A second particle (polystyrene microparticle with Europium) is conjugated with the second or detection MAb. In the diagnostic device shown in FIG. 30, the hash marks on the side of the diagnostic device (slide) are indentations molded into the plastic, which may be used as cog grooves. Additionally the slide is designed to fit into a processor that may have more than one processing station, as shown in FIG. 32.

In performing a method of detecting a diagnostic marker using an embodiment of the diagnostic device, such as that in FIGS. 30 and 32, the user adds a pre-determined amount of specimen (such as 120 μl) to a specimen diluent (such as 40 to 120 μl), and adds the mixture to each test well. Following addition of the diluted specimen, the test slide is incubated at 37° C. for about 5 to about 15 minutes with agitation. Following the incubation period, the test wells move over a magnetic source that brings the PmMp to the bottom of the well, so that there is maximal binding of the PmMp with the anti-haptin bound in the test well. Next, specimen and assay reagents are removed, wash buffer is added and aspirated off. Lastly, each well is scanned using a visualization device, such as a CCD camera, and then the fluorescent signal (or other signal) of each marker is determined.

14. Fluid Collection Device

An example of a collection device for the collection of an bodily fluids is depicted in FIG. 31. In this example, the collection device is capable of collecting at least 500 μl of bodily fluid, such as saliva. The cap is first removed from the tube. Squeezing the bulb provides suction adequate to pull an amount of saliva into the bulb. In some cases, a filter may be included in the tube to remove unwanted materials (such as particulate and mucous). The filter may be of any known filter material, such as rayon, that is appropriate for the purposes described herein. Following the obtaining of the bodily fluid in the collection device, a cap is placed on the tube, and a second cap is removed from a dispensing tube. The dispensing tube is in fluid communication with the bulb and is sized and shaped to allow for drops of a predetermined size to be formed when the bulb is squeezed. For example, the dispensing tube may allow drops of 30 μl to be formed when the bulb is squeezed.
